Title: Improved grinding wheel for flat glass beveling
Inventor: RAMANATH SRINIVASAN
IPC: B24D3/28
Filed: 1996-02-21
Abstract: A composite, polymer bonded abrasive wheel is disclosed for grinding operations and especially for use with multiple station, glass beveling machines. The abrasive wheel breaks in quickly and delivers consistent performance with little or no dressing needed over the entire life of the wheel. In one aspect, the novel abrasive wheel includes a concentrically mounted, annular abrasive rim on a cup shaped hub. The rim can contain an abrasive such as diamond or cubic boron nitride which is embedded in a bonding composition that includes amino aldheyde and phenolic thermoset polymers, a plasticizer, and optionally filler. The hub includes a crosslinkable, strong and rigid, engineering polymer, preferably melamine phenolic thermoset polymer, mixed with spodumene in amount effective to make the coefficient of thermal expansion of the hub match that of the rim. The wheel can be made by simultaneously hot pressing rim and hub preforms and without an additional baking step. Optionally the rim and hub can be colored to identify the characteristics of the abrasive, and to help determine that the grinding surface has worn down to the hub.

Title: Electric current switching apparatus with unitized removable contacts
Inventor: BAUER MICHAEL E
IPC: H01H9/34
Filed: 1997-10-03
Abstract: A sealed contactor for switching electric current has a switching assembly that includes a movable contact which selectively bridges a pair of stationary contacts to provide an electrical path therebetween.  The moveable and stationary contacts are mounted to a body of electrically insulating material to form a unitized structure.  A separate actuator assembly has an enclosure which contains an electrically operated driver with a linkage that extends into the switching assembly to alternately operate the moveable contact into engagement with and disengagement from the stationary contacts.  The switching assembly is sealingly attached to the actuator assembly in an interlocking manner that prevents arcs produced between the contacts from escaping outside the electric current switching apparatus.          Nevertheless, the switching assembly is capable of being easily removed and replaced as a single unit from the actuator assembly when repairing the contactor.
Patent CA-2217886-A1 (CA)
Inventor: FORSYTH IAN J
IPC: H02M5/458
Filed: 1996-04-15
Abstract: A device for controlling an AC output with an AC load from an AC supply comprises a power amplifier module connected to the AC supply and a control module in communication with the AC supply and the power amplifier module. The power amplifier module converts an AC supply to DC and then converts the DC to an AC output. The control module extracts predetermined characteristics, such as current, voltage and frequency from the AC supply and compares the predetermined characteristics with stored load characteristics of the AC load. The control module responsively triggers the power amplifier module to generate an output waveform of the AC output substantially in phase with respect to the AC supply.

Patent CA-2224200-A1 (CA)
Inventor: SHEENA HUSAM
IPC: C08L51/06
Filed: 1996-06-07
Abstract: A process is described for preparing graft copolymer by reacting (i) a thermoplastic hydrocarbon polymer, (ii) a C4 dicarboxylic acid or its amide, imide, or anhydride, and (iii) a comonomer containing two or more ethylenically unsaturated polymerisable groups copolymerisable with the thermoplastic hydrocarbon polymer. The reaction is carried out in an internal mixer in the presence of a free radical generator while applying shear to the molten polymer. The resulting graft copolymer can then be reacted with a hydrophilic organic filler, such as starch. In a variant of this process the graft polymerisation reaction is conducted in the presence of a hydrophilic organic filler. The resulting filler-grafted thermoplastic hydrocarbon polymer can be admixed with further thermoplastic hydrocarbon polymer and/or hydrophilic organic filler.

Title: Protecting confidential information in a database for enabling targeted advertising in a communications network
Inventor: GIFFORD WARREN STANTON
IPC: G06Q30/06
Filed: 1996-06-10
Abstract: Protecting a database against the deduction of confidential values contained therein is accomplished by partitioning the database into public and private values (202), some of which public values are deemed more important than others (203). The private attribute values are electronically processed (204-226) to reduce any high correlation between the public values and the private values. Specifically the processor partitions the database (204-210) into safe tuples and unsafe tuples, which unsafe tuples have high correlative public values (216-218). The processor then selectively combines the public attribute values of the tuples (220) to camouflage such tuples from deduction of their private attribute values beyond a threshold level of uncertainty (226).
